SPECIFICATION forming part of Letters Patent No. 696,782, dated April 1,1902.

Application filed July 10, 1901.

To all whom it may concern.-

Be it known that we, JOHN C. WooDY, of Mount Vernon, in the county ofPoseyand State of Indiana, and WILLIAM R. DANLEY,

of Denver, in the county of Arapahoe, and WILLIAM H. YOUNG, ofRockyford, in the county of Otero, State of Colorado, citizens of theUnited States, have invented newand useful Improvements inDriving-Gears, of which to the following is a full, clear, and exactdescription.

The invention relates to treadle-power for actuating small machines,such as sewingmachines, coffee-mills, and the like. The object of theinvention is to provide a new and improved driving-gear which is simpleand durable in construction, very efiective in operation, and arrangedto directly actuate the machine to be driven and to support the same onthe main frame.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a side elevation of the improvement. Fig. 2 is a plan viewof the same. Fig. 3 is a rear end elevation of the same. Fig. 4: is adetail section on the line 4 4 of Fig. 1,-and Fig. 5 is a detail sectionon the line 5 5 of Fig. 1.

The improved driving-gear is mounted on a frame consisting, essentially,of spaced longitudinally-extending bars A A, connected at their forwardends with a platform B, having legs 0, and the rear ends'of the saidbars A' are secured to a standard D, resting at its lower end on thefloor the same as the legs 0, to hold the bars A A and the platform Bapproximately in a horizontal position. 7

On the platform B is bolted or otherwise secured a bearing E forcarrying a machine F to be driven, and the upper portion of the saidbearing E is connected bya brace G with the upper end of the standard D,the brace being preferably made of telescopic sections G and G fastenedtogether by suitable set- Serial No.67,'708. (N0 model.

screws G A center brace H also extends from the upper end of thestandard D to the bars A to meet the latter at or near the middlethereof, and adjustable legs I are secured to the bars A directly belowthe connection of the center brace II with the said bars.

On the bars A between the legs I and the standard D is mounted to slidelongitudinally a bearing J, in which is journaled a crankshaftK,carrying crank-arms K, supporting pedals K adapted to be engaged by thefeet of the operator seated on a seat L, having its seat-post Lvertically adjustable in the up per end of the standard D, the postLbeing secured in place after the desired adjustment is made by aset-screw L The operator seated on the seat L takes hold of a handle-barN, longitudinally adjustable on the upper part G of the brace G. On thecrank-shaft K centrally between the bearings is fastened asprocket-wheel 0, connected by a sprocket-chain O with a sprocket-wheel0 secured on the main shaft F of the machine F to be driven, the saidshaftbeing journaled in the bearing E and provided at its end withsuitable fly-wheels F Now in order to give the desired tension to thechain 0 the bearing J is made adjustable, and for this purpose ascrew-rod J and nut J 2 are provided 8b to adjust the bearing Jlongitudinally on the bars A.

By connecting the several parts of the frame with each other, asdescribed, a very rigid and durable frame is secured, and by having theupper brace G adjustable proper adj ustment can be made between thestandard D and the bearing E. This arrangementof the brace G is of greatutility, as it allows for adjustment to suit the machine to be operoated and permits of securely bracing the machine against strain from thechain, thus taking all strain from the fastening devices that secure themachine to the platform and preventing jarring. 7

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. A driving-gear, comprising a frame arrangedto support the machine to be driven, a crank-shaft having crank-armsprovided with pedals, bearings for the crank-shaft adjustable on theframe, a sprocket-chain and sprocket-wheel connection between thecrankshaft and the main shaft of the machine to be driven, thesprocket-wheel being arranged centrally between the bearings, a seat onthe said frame, a brace connected with the frame below the seat andadapted to engage the machine to be driven, the brace being adjustablein length to suit the machine to be operated, and to brace the sameagainst strain from the chain, and a handle-bar on the said adjustablebrace, as set forth.

2. A driving-gear, comprising a frame having longitudinal spaced bars, aplatform at the front end of the bars for supporting the machine to bedriven, a crank-shaft having crank-arms provided with pedals, asprocketchain and sprocket-wheel connection between the said crank-shaftand the main shaft of the machine to be driven, a standard at the rearend of the bars, a seat carried by the said standard, a handle-bar onthe frame, the bearings of the crank-shaft being mounted to slidelongitudinally on the spaced bars in front of the standard, and meansfor adjusting the bearings, as set forth.

3. A frame for a driving-gear, comprising longitudinal spaced bars, aplatform on the front end of the bars, legs for supporting the frontends of the bars and platform, astandard at the rear ends of the bars,bearings on the said platform for supporting the machine to be driven,an upper brace connecting the bearings with the standard, the said upperbrace being adjustable in length to compensate for changes in theposition of the bearings and a center brace connecting the standard withthe said bars, as set forth.

4. A frame for a driving-gear, comprising longitudinal spaced bars, aplatform on the front end of the bars, legs for supporting the frontends of the bars and platform, astandard at the rear end of the bars, abearing adapted to be secured on the said platform for supporting themachine to be driven, an upper brace adapted to connect the standardwith the said bearing, the brace being made in sections and adjustableto suit the position of the machine to be operated, a center braceconnecting the standard with the said bars, and a set of adjustable legson the said bars below the point of connection of the center brace withsaid bars, as set forth.

5.v A frame for a driving-gear, comprising longitudinal spacedbars, aplatform on the front ends of the bars, legs for supporting the frontends of the bars and the platform, a standard at the rear ends of thebars, bearings on the said platform for supporting the machine to bedriven, an upper brace connecting the bearings with the standard, thebrace being made in telescopic sections fastened together whereby it maybe adjusted to suit changes in the position of the bearings 011 theplatform, and a center brace connecting the standard with the said bars.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
